Method and system for intelligent maintenance
First Claim
1. A method for reconfiguring an operational system having a plurality of input parameters and a plurality of output parameters, comprising:
- obtaining a maintenance schedule of the system;
obtaining a set of actual values of the plurality of input parameters and corresponding actual values of the plurality of output parameters;
calculating corresponding model values of the plurality of output parameters based on an established process model indicative of interrelationships between the plurality of input parameters and the plurality of output parameters;
determining a divergence trend based on current divergences between the actual values and the model values of the plurality of output parameters;
determining a desired set of values of the plurality of output parameters based on the divergence trend and the maintenance schedule; and
providing a desired set of input constraints required to achieve the desired set of values of the plurality of output parameters based on the divergence trend and maintenance schedule.

Abstract
A method is provided for reconfiguring an operational system having a plurality of input parameters and a plurality of output parameters. The method may include obtaining a maintenance schedule of the system and obtaining a set of actual values of the plurality of input parameters and corresponding actual values of the plurality of output parameters. The method may also include calculating corresponding model values of the plurality of output parameters based on an established process model indicative of interrelationships between the plurality of input parameters and the plurality of output parameters. Further, the method may include determining a divergence trend based on current divergences between the actual values and the model values of the plurality of output parameters and determining a desired set of values of the plurality of output parameters based on the divergence trend and the maintenance schedule. The method may also include providing a desired set of input constraints required to achieve the desired set of values of the plurality of output parameters based on the divergence trend and maintenance schedule.
